portion 2v vis :preSsedagainst and iinoved.-.-along the .:piece; ;of: .wood ,being -.workd and shavings rontof the "blade I 0 and ran oppositely 1 disposed surface 14. As previously mentioned, the shavings removed by the cutting blade frequently jam tightly between the blade and the oppositely disposed surface l4 so as to completely choke the opening and interfere with or prevent further cutting. The usual blade aperture or slot has a permanently fixed width sufii-cient to accommodate normal blade adjustments and to permit passage of shavings up over the blade to the upper part of the plane. Making the slot permanently wider to prevent jamming of shavings is objectionable as it interferes with correct operation of the plane; that is, when the width of the aperture is increased enough to eliminate jamming of shavings the comer of a board or some other edge of the surface being planed may project into the releasing opening and prevent movement of the plane or result in a much greater cut being made than is desired. There are other objections to making the slot wider and those referred to are merely exemplary. With the present invention the opening between the blade ill and the op posite surface I4 is normally as shown in Fig. 4 but it may be readily enlarged to release jammed shavings; this releasing device will now be described.

As shown more particularly in Figs. 3 and 4 applicants plane is provided with an aperture that extends from a rear fixed edge l8 to a front fixed edge 19, as well as across the width of the plane between the upwardly extending side portions 4 and 5. This aperture is much wider than the blade slot of an ordinary plane. The large aperture may be partially closed by a member 20 that is rotatably mounted at its opposite ends on pins 22 and 23 which extend through the fixed side portions 4 and into suitable recesses in either the rotatable member 20 or an upwardly extending projection 22. In Fig. 5 the members for rotatably supporting the bottom member 20 are shown threaded into the fixed side portions 4 and 5, with reduced ends projecting inwardly from the side'portions. If desired, the mounting may comprise screws 25 and. 26, such as shown in Fig. 6. threaded into the rotatable member 20 or its upwardly extending projection 22. The bottom surface of the r'otatablemember 20 lies substantially flush with the undersurface l3 of the plane when in closed position. v

When in use. shavings removed by the cuttin edge l0 pass up over the blade in the same manner as with the usual plane. If shavings accumulate or jam into the space between the cutting blade and the oppositely disposed surface [4 the rotatably mounted member 20 which carries the surface l4 may be swung about its supporting pins to some open position such as indicated by the dot-dash lines of Fig. 4. In this relationship shavings may fall out of-their own accord. After the shavings are removed, the closure member 20 may be quickly swung back to closed position for use in the normal manner.

' To facilitate movement of the member 20 between its closed and open positions it is preferably provided with the upwardly extending operating projection '22 that connects through links 2| and 30 with levers 32 and 33, the levers being secured adjacent ends thereof to brackets 35 and 36, shown bolted or riveted to an upper surface of the plane's base. When the member 20 is in closed position the operating levers 32 and 33 he substantially along the bottom portion 2 of the base and retain the member 20 closed, through .the connecting links 29, 30 and operating projection 22. To open the member 20 and enlarge the aperture in front of the cutting blade III, the levers 32, 33 are swung upwardly and this swings the links to the dot-dash line position shown in Fig. 4 and simultaneously tilts the member 20 by applying force to its operatin projection 22,

Inwardly extending portions 31 and 38 carried by the levers 32 and 33 may be readily engaged with the fingers to lift the levers and preferably these inwardly extending portions are recessed at their undersides as indicated more particularly in Figs. 1, 2 and 4 so that a person's fingers may be easily inserted thereunder. As indicated in Fig. 1, upward movement of the levers may be limited by the inwardly extending portions 31 and 38 contacting shoulders 40 carried by the handle or knob I.

The links 29 and 30 which connect the levers 32 and 33 with the operating projection 22 may be separate members rotatably connected at their upper ends with the operating projection 22 or may comprise end portions of a rod which extends entirely through an aperture in the operating projection and has its end portions bent forwardly and thence inwardly so as to project through suitable apertures in the respective levers 32 and 33.

When the closure member 20 is in closed position a beveled edge 42 abuts against a correspondingly beveled edge 43 carried by a fixed base portion l5. When the plane is in use any shavings which pass up over the front of the blade or which tend to jam between it and the oppositely disposed edge tend to rotate the closure member about its supports so as to seat the movable beveled edge 42 firmly against the stationary beveled edge 43. There is no tendency for any cutting or jamming forces to open the member 20 and interfere with correct operation of the plane.

The levers 32 and 33 and links 29, 30 are pref erably so proportioned and connected that when the levers are down against the fixed portion I! at the front of the plane (Fig. 4) the axis of the connection 46 between the levers and links lies below, or at least substantially in line with, the axis of the rotatable connection 34 between the brackets, 35, 36, and the levers 32. 33. In this relationship the closure member 20 is held against opening by force applied thereto. It is necessary to lift the levers 32 and 33 and swing them about their rotatable connections 34 with the brackets before the closure member 2|! can be opened. While other means, such as cooperating recesses and projections on the levers and fixed portions of the base, may be employed to hold the parts in closed relationshi that described is preferred by reason of its simplicity and inexpensiveness.

It will be seen that the present invention provides new and improved means for releasing shavings or slivers which may become jammed in front of the cutting blade of a plane or the like. It is not necessary to use some auxiliary instrument in order to poke the shavings loose, nor is it necessary to change the blade settin in any manner. An operating lever may be quickly lifted upwardly so as to swing a closure member about its rotatable support and enlarge the opening through which the shavings pass. Shavings readily drop out of their own accord when the device is moved to its open position.

When the shavings are out of the way the operating levers may be easily moved back to closed position to thereby close all portions of the aperture, except for the required slot immediately in front of the cutting blade. when the actuating levers are in closed relationship down against the stationary portion at the front of the plane, they effectively retain the closure member against accidental opening. Any force applied by jammed shavings or the like immediately in front of the cutting blade do not rotate the closure member to an open position but merely force a beveled surface at the front thereof into even firmer engagement with a complementary surface on the stationary part of the plane.

The present invention is ofrelatively simple construction and operation and does not require complete redesign of a plane in order to incorporate it with the plane, it may be added to planes of usual construction with a minimum of changes thereto. The rugged simplicity of the present device insures its standing up well under conditions of rough usage and provides for its manufacture at relatively small cost. While the invention has been described largely for use in a wood plane, it will be clear that it is equally useful with and may be readily incorporated into other tools of similar nature.

As various changes may be made in the form, construction and arrangement of the parts herein without departing from the spirit and scope of the invention and without sacrificing any of its advantages, it is to be understood that all matter herein is to be interpreted as illustrative and portion of the base for retaining said link against movement to retain the projecting means and member in closed relationship with respect to said aperture.
